Installation

Downloads for all supported operating systems are available here.

Linux

On Linux platforms you will need pcscd installed and running to be able to communicate with a YubiKey over the SmartCard interface. Additionally, you may need to set permissions for your user to access YubiKeys via the HID interfaces. The relevant permissions are described here.

For some configurations running Wayland, copying an OTP to clipboard only works when the app has focus. If you are unable to reliably copy to clipboard from the systray icon, you can use a separate binary which take the payload to stdin by defining the environment variable _YA_TRAY_CLIPBOARD. Note that this must be an absolute path to a binary owned by root:root, and should not be world-writable. For example: _YA_TRAY_CLIPBOARD=/usr/bin/wl-copy.

Note	Only use a trusted binary, OTPs will be sent to this when copied to clipboard from the systray!
